Digitron 2024T - User Manual

Model: 2024T
Sensor: PT100 Class A
Connector Type: 4 pin TCM screw plug
Units: °C/°F
Operating Temperature: -10°C to +50°C
Operating Range: -196°C to +600°C
Accuracy of Unit Only: ± 1 Digit ( 0.1˚C Low scale; 1˚C High scale )
±0.2% of reading ±0.1˚C over range of -196˚C to +600˚C
Before Use
Please ensure this unit is suitable to application.
Check temperature range and thermocouple type to ensure suitability for application.
Power
The instrument requires two AA or equivalent cells. These are not supplied with the unit.
When the batteries require changing the following symbol will be displayed:
Please ensure the screws holding the battery compartment are firmly tightened when inserting or replacing batteries
to ensure the IP65 rating is maintained.
Press ON key to turn unit ON. Press OFF key to turn unit OFF.
The unit will switch OFF automatically after 12 minutes, unless any key is activated.
To disable automatic switch off, hold Key when the unit is being switched on. This will disable the automatic
switch-off function until the unit is switched off.
Hold Function
To enable the Hold Function, press the “Hold” button
Speedread
This is a function that gives an indicative reading within 14 seconds for poor thermal conductivity items. The use of
this function will reduce the accuracy to ±2˚C. For correct Speedread measurements the probe must be in good
thermal contact with medium under test prior to activating the function. A steep temperature gradient or wide
temperature and item under test are required. Speedread is suitable for core frozen food measurements and
hot/cold liquids. Good thermal contact is unlikely when a general purpose or between pack probe is used on the
surface of food produce. (Not suitable for use with between pack probe).
Insert probe and press key. The symbol will appear and the display will flash fast until the correct reading
appears and the symbol will be displayed. This reading will automatically be held. Press key to return to normal
mode. If it is not possible to obtain a faster reading due to the similarity of probe tip temperature and the
temperature of item to be measured, then the symbol will be cancelled and the instrument will return to normal
mode.
C/F˚C Selection
Select the desired temperature scale by pressing key. The selected scale is confirmed by ˚C or ˚F symbol on the
display, and is retained when the instrument is switch off.
Range lock
All instruments have a 0.1˚ resolution from -199.9˚C to+199.9˚C and a 1˚ resolution outside this range. To fix the
display to a 1˚ resolution, press the A/R key. To cancel the mode, press the A/R key again and A/R will be shown on
the display.
